Abstract: 376,966. Separating and sorting gauges. SKERRETT, H. N., 24, Temple Row, Birmingham.-(Timken Roller Bearing Co.; Denber Avenue, Canton, Ohio, U.S.A.) July 28, 1931, No. 21489. [Class 106 (ii).] A machine for gauging conical rollers comprises a slidable work-receiving member having means for holding the work at one end, means having a predetermined stroke for operating the work-receiving member through the medium of the work, a single discharge shoot into which the work is delivered, and a series of gates controlling discharge outlets from the shoot, the gates being selectively operated according to the size of the roller. The main shaft 3 is driven through worm gear 4, 5 from a shaft 6 driven from a pulley 7 through a friction clutch 8. A lever 11 serves to operate a clutch 10, 9 for clutching the gear 4 to the shaft 3. A wheel 12 serves to operate the machine by hand. A sliding sleeve 13 has at one end a gauging socket 14 of the same taper as the rolls to be gauged, the other end being provided with a floating contact block 17 engaging a lever 18 pivoted in a housing 19 the supporting frame 22 of which may be vertically adjusted in the base 1 by operating a screw 25. The lever 18 is toothed at the free end to gear with a sector 27 spring-pressed against an open body lever 32 on the same pivot. The lever 32 has a toothed end part 36 gearing with a pinion 37 on the pivot of an indicator arm 38. The end of the lever 38 away from the pivot is connected by a link 45 to an arm 44 the boss of which is free on a stud 42 connected to the housing 19 but is connected to the stud by a coiled spring. Stop members 50, 55 fixed to the housing limit movement of the lever 38. The rolls are fed from a hopper through a tube 58 to the gauging socket 14. A lever 66 pivoted at 65 is rocked from a cam 68 on the shaft 3. An extension 70 of this lever, adjustably connected to it by a pin-and-slot device, carries a block 77 in which are pivoted jaw members 80 normally forced together by a leaf spring 81. A roll 16 passes between the jaws 80 and as the cam moves, the lever 66 and jaws are swung to bring the roll 16 into alignment with the socket 14, a stop member 83 preventing the roller sliding through the jaws. As the lever is swung, the stop 83 closes the mouth of the tube 58. A ram 84 pushes the roll 16 from the jaws 80 into the socket 14. The ram 84 has locked screw adjustment in a sleeve 85 slidable in bushings 86. A lever 90, on an adjustable pivot for varying the stroke of the ram, has one end engaging a cam 92 and the other end pivoted to the sleeve 85. Secured to a collar 88 on the sleeve 85 is an elongated arm 98 secured at the other end to a knock-out pin 99 that extends through the base of the sleeve 13 to eject a roll 16 on the return stroke of the ram 84. The latter has a fixed stroke and the member 13 is spring-pressed into position to receive the work. Thus when a roll is home in the socket 14, the final position of the member 13 will depend on the extent to which the roll protrudes from the socket and hence on its mean diameter. The indicating lever 38 carries an insulated contact member 100 connected to the return wire of an electric circuit the feed line of which is connected to a number of solenoids the return wires from which are brought to a series of insulated contacts 133 arranged in a sector on a carrier 120. This carrier is slidable in guides and is connected by a lever 115 to a shaft 108 rocked by cam mechanism from the shaft 3. After the indicator lever 38 has been positioned the carrier is moved so that one of the bank of contacts engages the contact 100 and the corresponding solenoid is energized and through its associated lever 135 moves up a gate member 106. The gates 106 are all assembled close together to form an inclined channel for the rolls and the one lifted exposes one of a'series of shoots into which the roll passes and hence to a receptacle. In setting the machine to gauge a batch of rolls, master " maximum " and " minimum " rolls are used to adjust the mechanism so that " uppermost " and lowermost " gates are actuated by these master rolls.
